At my Whole Foods store, they have a brand called "Peanut Wonder" - same nutrition, 100 cals for two tablespoons.
At first bite, I was disappointed that it didn't taste like full-fat, "real" peanut butter. But I used it anyway, and lo-and-behold, I love it now. I eat it on 40 cal. bread with sf strawberry jam, with apples, celery, and (gasp) even on a spoon.
Maybe it's an aquired taste? I've found it to be worthwhile!
